Advantages:
1. Can store "n" number of same data types in different indexes
2. Can be accesses using reference.
Disadvantage:
1. No boundary check, if the array boundary is crossed run time
2. No facility to increase the size of array in Run time

∙ 13y agoThe only advantage I can think of using an array (a collection that with a fixed size) is the initialization of each element in that array is set to the default value when the array is created (allocated), while a List (or a collection) with size can change does not get initialized to the default value even you set an initial size to it.
For example:
int[] array = new int[20]; // all 20 elements are 0, the default value of int
Exception[] errorArray = new Exception[10]; // all 10 elements are null
List<int> integerList = new List<int>(20); //cannot access to integerList[0] unless integer[0] has been explicitly assigned with a value, or integerList.Add() has been called at least once without being cleared
The disadvantage of using an array is the objects are being referenced/stored within, which may not easily being cleared, especially for those reference types.

What is the purpose of using arrays in C language?
The purpose of using arrays in C is to store multiple values in one variable. Then you can make programs that use arrays like lists, printing values from multiple arrays into one line. It take memory in continues block then we can know memory location easily. We can retrieve data quickly.
Are arrays in C created on the stack or the heap?
That depends on where you define them. Arrays defined inside functions are declared on the stack (like other variables defined in functions). Arrays defined outside of any function, or using the static keyword inside a function are allocated in the static data area of the program. Other arrays may be allocated using malloc() (or "new" in C++); these are allocated on the heap.

What are the notes for the c sharp harmonic scale?
C sharp, D sharp, E natural, F sharp, G sharp, A natural, B sharp & C sharp We call the note C "B sharp" to avoid using the same letter name twice. If we used the note name "C" we would have 2 C-notes and no B-notes in the scale!
